Products

What types of screws can I enquire about?

Our product range covers roofing, wood and structural, light steel framing, decking and concrete screws, together with self-drilling and self-tapping families. Choose the nearest product type, or send a drawing or photo if you are unsure.

Specifications

Which material or finish should I specify?

Include the materials being fastened, exposure conditions and any required material or finish. Availability and supporting technical information are confirmed for the selected screw; a finish shown elsewhere does not apply automatically to every product.

Can I discuss a screw based on a drawing or sample?

Yes. Send the drawing or a clear sample reference, including dimensions, head, point and thread details where available. The sales team can review the request and confirm the feasible specification and order requirements.

Where can I view reports or request product documents?

Reports & Documents contains the named Class 3 and Class 4 sample-report image sets and a historical internal salt-spray record excerpt. For another product or document, send the product name and the information you need with your enquiry.

Does a catalogue size range mean every size is available?

A catalogue range describes a product family. Specify the exact diameter and length, together with the head, point, material and finish, so the available configuration and order terms can be confirmed.

How should I use the head, drive, point and thread guides?

Use the source illustrations to describe the shape you need, then send a drawing or sample reference. Some labels repeat or need clarification, and the drawings are not to scale or a list of interchangeable standard designs.

Can I request tensile, shear or other inspection information?

Tell us the product, connection and test or document required. We will review the relevant tensile, shear, pull-out, torque, hardness or corrosion information and confirm the inspection arrangement for the order.

Can I specify a washer assembly?

Yes. Include the washer material, dimensions and assembly requirement with the screw specification. The feasible screw-and-washer combination, packaging and order conditions will be reviewed with your enquiry.

Packaging

Can I request head marking or branded packaging?

Head marking, labels, boxes and outer cartons can be discussed with your enquiry. Provide artwork and packing requirements; the final format, quantity and any applicable conditions are confirmed for the specific order.

Purchasing

What are the minimum quantity and lead time?

Minimum quantity and timing depend on the product, specification, packaging and order quantity. Include these details and the delivery destination in your enquiry so the applicable terms can be confirmed in the quotation.

What happens after I send an enquiry?

The next steps are to clarify the specification, review the quotation and agree the order details. Keep your drawing, packaging requirements and destination available so any outstanding questions can be resolved with the sales team.
